10.2 Initial Decision Maker, Communication Protocols & Project Records

1. The Initial Decision Maker (IDM) & Impartiality Standard

Under AIA Document A201 (introduced in the 2007 edition and reinforced in 2017), claims, disputes, and matters in question between the Owner and Contractor are referred initially to the Initial Decision Maker (IDM).

Designation & Standard of Impartiality

• Default Entity: The Landscape Architect (or Architect) serves as the IDM by default unless the Owner and Contractor mutually designate a separate independent third-party IDM in the Agreement.
• The Standard of Impartiality (AIA A201 Section 15.2.1): The IDM is contractually mandated to render decisions impartially, showing favor neither to the Owner nor to the Contractor. Even though the Landscape Architect is hired, paid by, and serves as an agent of the Owner during general administration, the moment the landscape architect assumes the role of IDM, they must operate with judicial objectivity.

IDM Claims Procedure & Timelines

1. Receipt of Claim: Upon receiving a formal written claim from either party, the IDM has 10 days to take one or more preliminary actions:
   • Request additional supporting data or narrative from the claimant.
   • Reject the claim in whole or in part, stating reasons.
   • Recommend approval of the claim to the other party.
   • Suggest a compromise.
   • Advise the parties that the IDM is unable to resolve the claim due to lack of sufficient information or because it involves legal questions outside design expertise.
2. Final Preliminary Decision: The IDM must render a written decision within 30 days of receiving the claim (or within 30 days of receiving requested additional data). The decision must state the reasons and notify parties of any change in Contract Sum or Contract Time.
3. Condition Precedent: The IDM's preliminary decision is a mandatory condition precedent to mediation. Neither party can initiate mediation, arbitration, or litigation without first receiving the IDM's decision or waiting 30 days after claim submission without an IDM response.

2. Communication Protocols & Command Chains

Strict contractual protocols govern project communications during construction. Bypassing established command chains creates severe liability, causes misdirected instructions, and invalidates contractual warranties.

Primary Rules of Project Communication

1. Owner-to-Contractor Communication (AIA A201 Section 4.2.4): Except as otherwise provided in the contract documents, the Owner and Contractor must communicate with each other through the Landscape Architect. Direct side-agreements, verbal promises, or field instructions from the Owner directly to the General Contractor bypass the design professional's coordination, create conflicting site directions, and expose the Owner to inflated change order claims.
2. Design Subconsultant Communication: Subconsultants retained by the Landscape Architect (such as civil engineers, structural engineers, or irrigation specialists) must route all field observation reports, technical clarifications, and submittal reviews through the Prime Design Professional (Landscape Architect). Subconsultants must never issue direct written or verbal instructions to the General Contractor or subcontractors.
3. Subcontractor Communication: Trade subcontractors (e.g., stone masons, landscape installers, earthmovers) must direct all questions, submittals, and notices through the General Contractor. If a subcontractor approaches the Landscape Architect on site asking for permission to alter planting depths or paver bedding thicknesses, the landscape architect must direct the subcontractor to consult the GC site superintendent.

3. Site Documentation, Field Reports & Project Directories

Thorough, contemporaneous written records are the landscape architect's primary legal defense against claims and regulatory investigations.

Field Observation Reports (AIA Document G711)

Following every site visit, the Landscape Architect must prepare and distribute a formal Field Observation Report within 24 to 48 hours. The report must objectively record:

• Date, exact arrival/departure times, and current weather conditions (temperature, precipitation, wind, recent freeze/thaw events).
• Persons present on site (owner representatives, contractor personnel, active subcontractors, testing lab technicians).
• Physical work in progress and observed percentage of completion by trade.
• Observations regarding general conformance with Contract Documents.
• Specifically identified non-conforming work or field deficiencies, cross-referenced to drawing detail numbers and specification sections.
• High-resolution photographic documentation with date, time, location, directional orientation, and descriptive captions.
• Status of previously reported deficiencies (corrected, ongoing, or unresolved).

Core Administrative Tracking Logs

The Landscape Architect must maintain rigorous, up-to-date tracking logs throughout the CA phase:

• Submittal Log: Tracks submittal numbers, specification sections, revision numbers, dates received, dates transmitted to consultants, dates returned to GC, and action codes taken.
• RFI Log: Tracks RFI numbers, subject descriptions, dates received, required response dates, consultant coordination notes, dates answered, and whether a cost/schedule impact was indicated.
• Change Management Log: Tracks Proposal Requests (PR), Construction Change Directives (CCD), and executed Change Orders (CO), recording financial amounts and calendar day adjustments.
• Testing & Inspection Log: Documents all field compaction test results, concrete cylinder breaks, nursery plant delivery inspections, and topsoil testing certifications.

5. Real-World Case Scenario: The Tree Protection Encroachment

Scenario: During a routine site visit for a new corporate campus arboretum, the landscape architect observes that the grading subcontractor has dismantled a 50-foot section of chain-link Tree Protection Zone (TPZ) fencing. A heavy tracked excavator is actively excavating a drainage trench within 6 feet of the trunk of a 48-inch DBH champion white oak (Quercus alba) designated for absolute preservation on Sheet L-101. Soil and fuel drums are stockpiled across the tree's Critical Root Zone (CRZ). The subcontractor informs the landscape architect that the civil engineer verbally told them during yesterday's utility walk-through that shifting the trench was acceptable.

Contractual Analysis & Resolution:

1. Means and Methods vs. Protection Enforcement: The landscape architect cannot physically commandeer the excavator or order the equipment operator to turn off the engine, as doing so trespasses on contractor means, methods, and site safety.
2. Immediate Administrative Action: The landscape architect immediately locates the General Contractor's Site Superintendent, points out the violation of Section 31 10 00 (Site Clearing) and Section 01 56 39 (Temporary Tree and Plant Protection), and issues a formal written field notice rejecting the excavation within the CRZ.
3. Subconsultant Breach: The civil engineer had no legal authority to verbally authorize a trench realignment directly to a subcontractor. All subconsultant directives must route through the Landscape Architect as prime professional.
4. Arborist Assessment & Owner Notification: The landscape architect immediately notifies the Owner and orders the project consulting arborist to the site to inspect root damage. The landscape architect recommends that the Owner issue a partial Stop Work Order in the vicinity of the tree until root pruning, pneumatic air-spading, and fence restoration are executed per specifications, with all arborist fees back-charged to the General Contractor.

6. Exam Traps & Pitfalls

1. The "Stop Work Order" Trap: Exam questions frequently present a contractor performing egregiously defective work and ask what the landscape architect should do. The trap choice states: "Immediately issue a Stop Work Order to the contractor." This is legally incorrect. Only the Owner has the contractual right to stop work (AIA A201 Section 2.4). The landscape architect can only reject the non-conforming work and advise the owner in writing to issue a stop work order.
2. The "Means and Methods" Trap: Any answer option that has the landscape architect directing how to shore a trench, which equipment to use, how to brace a retaining wall, or in what order to sequence trades is an immediate distractor. The contractor maintains sole control over means, methods, and safety.
3. The IDM Impartiality Trap: Exam scenarios will test whether the landscape architect, when acting as IDM, should protect the owner's budget or side with the owner because the owner pays their fees. Under AIA A201 Section 15.2.1, the landscape architect must remain strictly impartial, deciding claims based solely on the Contract Documents and the facts.
4. The Direct Subcontractor Communication Trap: When a subcontractor identifies a conflict or requests a change, the landscape architect cannot issue a direct instruction to that subcontractor. All formal communication must flow through the General Contractor.
